Independent app studio · Brisbane, Queensland, Australia

We make apps people keep.

Alt Dev Apps designs, builds and runs its own apps from Brisbane: a daily colouring contest, a shared baby tracker, and an energy agent that answers to you. Three apps, each run end to end by the people who wrote it.

The apps

Designed, built and run by Alt Dev Apps

Read about all three apps

What we build

Three apps, run properly

Alt Dev Apps is the studio behind all of them. Each app has its own website, its own store listings, its own policies and its own support address, and the same registered Australian entity stands behind every one.

How we work

A small studio on purpose

Being small is the strategy, not a stage we are trying to grow out of. It is what lets us support the software we write.

We run what we build

The same small team designs, builds, ships and supports each app. When you email support, you reach someone who can change the code.

Made in Australia, for here first

Built around Australian rules and regulators, supported in Australian business hours from Queensland, and hosted in Australian regions wherever a provider offers one.

Privacy is the default

Each app collects what it needs to work and nothing more. We never sell customer data, and every third party this website loads is named in its privacy policy.

Made to still be here later

Self-funded and deliberately unhurried. We would rather run three apps properly for a decade than launch six and abandon four.

Writing

What we have learned building here

Notes on building and running apps from Australia, written when we have worked something out properly rather than on a schedule.

BubSync is live, and it started at 3am

Our shared baby tracker launched on Google Play and the web on 5 September 2026. Why it exists, what it does, and what building it taught us.

Shipping with a small team, including the AI part

The pipeline, the deliberately boring technology choices, where coding assistants genuinely help, and what a two-person company has to leave out.

Compliance is product work, not paperwork

Consumer guarantees, subscription rules, app store policy, GST and accessibility, and how each of them changes what you actually build.
